nikolayasdf123··on Waitgroups: What they are, how to use them and what changed with Go 1.25
> wg := sync.WaitGroup{}

just `var wg sync.WaitGroup`, it is cleaner this way

nikolayasdf123··on RFC 9839 and Bad Unicode
how does this compare to Go `unicode.IsPrint(r rune)`? https://pkg.go.dev/unicode#IsPrint

what does bad/dangerous this code catch that `unicode.IsPrint` is not catching?

or other way, what good/useful does `unicode.IsPrint`removing, that this code keeps?

nikolayasdf123··on RFC 9839 and Bad Unicode
interesting. isn't in Go it is just `unicode.IsPrint(r rune)`? https://pkg.go.dev/unicode#IsPrint

wow, that's a lot of people for such a product. what are you all doing there? seems seriously over-hired.

or maybe don't. all founders I know are cutting on every single dollar. zero-subcriptions is a trend now.

how many different / how specific use cases will actually be build with this AI?

their demo "Task Management", "Budget Tracker" — all cliche and trivial. nothing new or specific here. build it once and re-use for everyone.

nikolayasdf123··on Go is still not good
I 80% of time use structs. common misunderstanding: it does not reduce performance for pointer vs value receivers (Go compiler generates same code for both, no copy of struct receiver happens). most of structs are small anyways, safe to copy. Go also automatically translates value receivers and pointer receivers back-and-forth. and if I see pointer I see something that can be mutated (or very large). in fact, if I see a pointer, I think "here we go.. will it be mutated?". written 400,000 LOC in Go, rarely seeing this issue.

if this is the worst, not too bad.
nikolayasdf123··on Launch HN: Channel3 (YC S25) – A database of every product on the internet
OpenAI and Perplexity is notoriously getting sued by NYT, newspapers in Japan.

all do the same, which may be the reason why web is going to "close up", to prevent leaking data like this.

might be selective bias. try talking to folks who blocked scraping and you scraped them anyways and resold their data. see how happy they are. or try to talk to amazon, ebay, facebook for scraping their data, see how happy they are too.

> and often lives behind advanced bot-detection systems.

for a purpose. they own that data. now you are scraping and re-selling it. how you think they will like that? expect court orders and cease and desist letters coming in.

dangerous business. when it does not work, nobody cares. when it works, you gonna get sued by markeplaces/vendors you were scraping (e.g. amazon, etc.).
nikolayasdf123··on Launch HN: Channel3 (YC S25) – A database of every product on the internet
no way. how are you not gonna get sued by them?
nikolayasdf123··on Launch HN: Channel3 (YC S25) – A database of every product on the internet
yes, really expensive. I would pay something like USD 0.01 / 1K requests... and even then, privacy and data ownership (even of queries themselves) is serious concern. especially you are just scraping other websites and re-selling their data. so why would I trust you with my data and funnel then?
nikolayasdf123··on Launch HN: Channel3 (YC S25) – A database of every product on the internet
so you are scraping other vendors and online marketplaces? aren't you afraid getting sued by them? (e.g. by amazon?)

> personal foundry anytime soon

pretty sure top 1% of say USA already owns much more than that

nikolayasdf123··on AI is different
Internet did not take away jobs (only relocated support/SWE from USA to India/Vietnam)

these AI "productivity" tools straight up eliminating jobs. and in turn wealth that otherwise supported families, humans, and powered economy. it is directly "removing" humans from workforce and from what that work was supporting.

not even hard takeoff is necessary for collapse.

nikolayasdf123··on AI is different
probably "or worse"
